Abstract

(57) [Abstract] [Purpose] To provide a structure for fixing a terminal portion of a seat cover capable of reducing the number of work steps and the number of parts. [Structure] Slits 6 are arranged on the end portion of the seat cover 2 so as to correspond to the convex portions of the S spring 4. A tear preventing portion 7 is provided at both ends of the slit 6. Then, at the time of seat assembly, after covering the cushion body 1 with the seat cover 2, the slit 6 is hooked and fixed to the convex portion of the S spring 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing structure for a terminal portion of a seat cover applied to a vehicle seat or the like, and more specifically, a fixing structure aiming at reducing the manufacturing cost by reducing the man-hours required for assembling the seat cover and the number of parts. Regarding

[0002]

[Prior art]

 FIG. 4 is a perspective view showing the back surface of an automobile seat cushion. A cushion body 1 made of a pad material, an S spring and the like is covered with a seat cover 2 such as cloth as a skin material. The terminal of the conventional seat cover 2 is fixed to the S spring 4 by using the hog ring clip 3 or the like on the back surface of the cushion body 1. FIG. 5 shows a cross section taken along the line BB of FIG. 4, in which the edge trim 5 is sewn to the end of the seat cover 2 to reinforce the hog ring clip 3 which penetrates the inside of the edge trim 5. After hooking on the S spring 4, the terminal was fixed by tightening the clip in a ring shape.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional structure, there is a problem that the number of parts is large, such as requiring a hog ring clip and edge trim. Further, in addition to sewing the edge trim, at least about 6 hog rings are required, which causes a problem that a lot of work man-hours are required for the assembling.

Moreover, since the hog ring clip is hooked on the S spring, there are many inconveniences such as the occurrence of abnormal noise due to the contact between the hog ring clip and the terminal of the hog ring clip causing a feeling of harm. Improvement was also desired in order to improve.

Therefore, an object of the present invention is to reduce the manufacturing cost by reducing the number of parts and assembling steps, and at the same time, to improve the occurrence of abnormal noise to provide a highly commercial sheet seat terminal. It is to provide a fixed structure of the part.

[0006]

[Means for Solving the Problems]

 The present invention solves the above-mentioned problems, and in the terminal part fixing structure of the seat cover that covers the outer periphery as the skin of the cushion body provided with the S spring, the position corresponding to the convex part of the S panel near the terminal part. The seat cover terminal portion fixing structure is characterized in that slits are arranged on the sheet spring, and the slits are directly hooked to the S springs to be fixed.

[0007]

[Action]

 According to the above-mentioned means, the slits arranged at the end portion of the seat cover can be easily fixed by a simple work of directly hooking the convex portion of the S spring, and the number of parts and the number of work steps can be reduced. .

[0008]

【Example】

 An embodiment of a fixing structure of a seat cover terminal according to the present invention will be described with reference to FIGS.

FIG. 1A is a perspective view showing a back surface of an automobile seat cushion, and a seat cover 2 sewed in a bag shape is covered as a skin material of the cushion body 1. At the end of the seat cover 2, slits 6 are arranged at positions corresponding to the protrusions of the S spring 4 of the cushion body 1, and the slits 6 are hooked and fixed to the protrusions of the S spring 4. (See FIG. 1B). The end portion of the seat cover 2 is generally folded back and sewn together, and thus the slit 6 is formed in the portion where the two skin materials are overlapped. Then, in order to prevent the slits from spreading more than necessary at both ends of the slit 6, it is preferable to provide a tear preventing portion 7 cut out in a substantially circular shape, for example (see FIG. 2). Further, as shown in FIG. 3, the break preventing measure may be a straight break preventing portion 8 that is substantially orthogonal to the slit 6.

With the seat cover terminal fixing structure as described above, when the seat cover 2 is assembled, the slit 6 is attached to the S spring 4 after the bag-shaped seat cover is covered on the cushion body 1. Since it only needs to be hooked on the convex portion, workability is greatly improved compared to the conventional structure. In addition, since a fixed part such as a hog ring clip is not required, it has a fixed structure with a small number of parts, and it is also effective as a measure to prevent the generation of harmful feelings and noise that was present in the conventional structure.

It is not necessary to provide the above-mentioned slits 6 corresponding to all the convex portions of the S spring 4, and it is sufficient if, for example, about 3 points at both ends and the central portion can be hooked. It goes without saying that it can be applied not only to the seat cushion but also to the seat back.

[0012]

[Effect of device]

 According to the fixing structure of the seat cover end portion of the present invention described above, the number of work steps and the number of parts can be reduced, so that the cost can be reduced.

Further, since it is possible to eliminate the feeling of harm and reduce the generation of noise, it is also effective in improving the commercial properties of the seat and the vehicle.
